IRM Expansions and Addons (CAM Edition) 1.1

I HAVE QUESTIONS.

 

Is it already christmas? Is "nos 17" the nick of santa claus? Is botox for sc4-industries even legal?  

 

Thank you! Thank you! Thank you!

I HAVE QUESTIONS TOO.

Although, first of all: Thank you! Thank you! Thank you!

So, my questions are about the Quadrupled use with CAM. I'm new to CAM and I've just came back to SC4 after an hiatus of a few years, so, please bear with me.

I used the Quadrupler by toroca with the non-CAM IRM before. Recently, I was using the Doubler by bones1, again with non-CAM IRM. In other words, I don't want massive industrial areas to support relatively small residential areas. But, CAM documentation specifically says that these mods are inCAMpatible and superfluous because industrial buildings have already been modified (some have been multiplied by 6). I don't know if that still applies when IRM CAM mod and/or this IRM CAM expansion mod are installed.

So, is the CAM industry job boost still in efect with CAM versions of IRM mod buildings?

In the meantime, I'm working my way with the dependencies of this mod. Thanks again!

So I think you're right, that CAM and quadrupler are incompatible. I'm hardly an expert here but I have done some more reading since, especially because another member shared exactly the same questions.  CAM + doubler/quadrupler are also modifying the same assets so they would be "doubly" incompatible. In their CAM 2.1 manual, @InvisiChem suggests the IRM (CAM version) is CAMpatible, the expansions and add-ons are probably CAMpatible, and anything PIMXd is also CAMpatible. This implies that my quadrupled versions are not CAMpatible (though there is no actual conflict with CAM - they are new exemplars and don't override any CAM content - they are just designed with values out-of-proportion with the rest of the industrial content).

I'm a little torn between keeping all of the options there (for people who may be already using IRM 4x'd, it probably is best for consistency), and taking them down. Either way, I think an update in the documentation is required. Curious on your thoughts.

Sadly, I have no idea about the technical aspects of modding. It's a shame that T Wrecks, InvisiChem and Shadowstrike are no longer active here, so maybe @Fantozzi and others can bring some light.

I am still wrapping my head around Shadowstrike's Industrial Revolution Mod - CAM Version and why it supposedly doesn't need the original IRM by T Wrecks to work. Shadowstrike said that the original IRM wasn't needed. I haven't had time to do serious tests, but this is what I've found so far:

CAM→IRMCAM-B: Industrial CAMeLots develop (CAMeLot counter). Industrial buildings have Maxis skin (One of the attractives of IRM is the way the buildings look. Loosing it is no good)

CAM→IRMbase→IRMCAM-B: Industrial CAMeLots develop. Maxis skin. (It looks like nothing changes if IRMbase loads before IRMCAM)

CAM→IRMCAM-B→IRMbase: Industrial CAMeLots develop. IRM skin. (This looks like it works as intended)

I haven't noticed any changes in workforce with any of the above combinations, but I didn't take notes, so maybe there are.

I was using the B version, but didn't check if only dirty industry was developing in medium density.

I don't know why Shadowstrike said IRMbase wasn't needed, because without it the game only displays Maxis style industrial buildings. Maybe at that time IRMbase-CAM included the lots too? Currently, the mod is just a small .dat file.

T Wrecks said this about the CAM compatibility of the IRMbase mod:

Quote

Is this mod compatible with the Colossus Addon Mod (CAM)? No. The CAM contains copies of all Maxis lots that have been assigned to different stages and given a different IID. That's why the IRM lots cannot override the CAM lots.

So, my guess is that IRMCAM overrides the CAM lots with CAMpatible properties. After that, IRMbase is there to make the buildings look as intended.

So, @nos.17, should your mod load after everything else? I.e.: CAM→IRMCAM→IRMbase→IRMexpaddonCAM?

Regarding the quadrupler/doubler issue, I think the right way is to keep gaming properties as close as possible to CAM specifications. Providing the option for 4x is fine, but players should be aware of any possible issues. Nevertheless, is the 4x applied to Maxis original numbers or to CAM numbers? Because if it is the latter, it could be game breaking.

I'm sorry to use this thread to raise so many questions about Shadowstrike's mod. But, since this is an expansion to it and Shadowstrike is no longer here, this thread may be the best place to discuss how everything interacts together. Anyway, please do not hesitate to let me know if you prefer to not discuss anything outside the expansion mod.

This was poorly worded. I am getting I-M in high density industrial areas. So B version, which supposedly would move all I-M to medium density allowing I-HT only in high, is not working. At least not with this loading order: CAM→IRMCAM→IRMbase

I already have all the buildings and dependencies for your mod @nos.17, at least the ones currently available to download. So, I am thinking about installing it to run some tests. Any suggestions?

This is correct. Shadowstrike's IRM CAM contains the exact same files as IRM Base, except with the values modified for CAM.

Yep! If you take a look inside that dat file there are 261 lots packed in there.

CAM overrides Maxis industry. IRM CAM overrides CAM industry. Thus the load order should be CAM → IRM CAM. Keep in mind that this expansion does not override anything included in the game from Maxis, or anything included in CAM - it is all overriding custom lots/buildings created by the community. If you throw this stuff in the same folder as the IRM CAM assets you'll be fine (as long as you don't keep the lots included in the dependency files here).

Try this without the IRM base. If its set up as you describe then IRM Base is overriding IRM CAM thus giving you back the original distributions of I-M.

Nope. Go for it!

It's a bit confusing because some related mods (including this one ) include both of them in the required dependencies; while others say one or the other.

I said I had no idea about the technical stuff, and I proved my point! XD. I made it work and now I have the version A of IRM-CAM withouth the original IRM base pack. I don't know why the version B alone wasn't working, but it was probably my fault.

This got me thinking. How does the quadrupler fit here? None of the SC4D LEX Legacy IRM CAMpatible packs available on SC4Evermore says nothing about compatibilities with multipliers, so I guess they are not designed to be used with any of them. But at least from what I have observed so far, their industries offer a lot more jobs than IRM-CAM industries. I guess this is a modding trade off, there aren't any real guidelines and every modder does what they want (which is totally fine, it is their mod after all) and PIM-X values still give plenty of room for big differences between buildings.

It's already running! I had to exclude a sizeable chunk of the buildings due to missing dependencies, but there is still a lot of good stuff left! I went for the version A (IRM standard separation) and standard job numbers too. Although I'm not going to have a lot of time available to play around because my parents are coming over to visit us. Not a lot of time to play, if any, until mid January.

Fair point. I did word that a little poorly. I'll get it changed.

It's my understanding that anything made with PIMX is automatically CAMpatible. PIMX uses a standard set of calculations to determine stats, and if you don't use PIMX to create lots (which I don't think T Wrecks did), there is no guarantee the stats will be consistent. The quadrupler arose because people thought the default Maxis job amounts were far too small, but the CAM/PIMX values are a good bit higher so I suppose the quadrupler is less relevant.

One important thing to note that I don't think has been mentioned elsewhere (and, probably, should be advertised more widely—all of T Wrecks's original uploads still link to obsolete SC4Devotion pages) is that, at least as of Version 7, the BSC Common Dependencies Pack contains all the models for JEStarr, Tag_One and JFMyers's buildings used in the IRM Expansions and Add-Ons. As far as I can tell, that means the only IRM Expansion files that currently require unavailable dependencies are the SFBT ones (H2O Chemistry, High Enthalpy Wind Tunnel and Maschinebau, all by Mathe Man).

Anyway this has encouraged me to try playing with CAM and IRM myself, which will evidently take some getting used to, but should be fun. Thanks for putting this together.

Good observation. I'll update the docs shortly.

Will the CAM and even Maxis industry lots grow with IRM CAM lots or not to add more variety? Or I'm reading it incorrectly.

I hope these will be available soon since SimCity Plaza isn't accessible!

Lastly, thanks for bringing these to Simtropolis after all these years! 

Hello, I just installed the IRM CAM and this expansion.

From what I understand, after you download and install this expansion, you have to go pick the missing 100+ .sc4model files and put them in each of the building you want to be available. Is that correct?

I tried to add just one for testing (IRM W2W Gaulargaten 15 By Glenni), indeed the cleantool script doesn't complain anymore, according to what you wrote about the script checking only the buldings you want.

Ok, fine, but it seems that for all the other buildings for whom you didn't provide the .sc4model, if you don't delete their directory, you get the dreaded "brown box". I did. I got a few NYBT ABBT 609 W 131st Street in my test city and they are all brown boxes.

I guess this is normal, since the model is missing, but I have a question now: why wasn't their .sc4 model directly added with each buidling? Why should whoever wants this very nice IRM expansion need to do that and find and put 100+ models there?

Please notice that I'm not complaining, I understand this modding is heavy work: it took me 1 full day to install all the mods from NAM, CAM, DLLs, many CAM stuff including the nightmare CAM agricolture and all their respective dependences and I probably did some mistakes and I'm gonna use SC4READER to check the failed dependences and it doesn't look good.

I say again, I'm not complaining and modding of any game is funny and heavy work, but I'm genuinely curious why this expansion requires to go hunt for all those .sc4model files, and at least takes the pain to correctly lists them with their link, when with basically the same work of listing those, they could have been included in the expansion zip file directly.
The author did such a wonderful job that I cannot believe it is laziness, so there should be another reason, but I can't figure which one. Would you satisfy my curiosity?

Oh, I also have to add that there is already one I cannot find the sc4model, the very first one in the list: IRM W2W Acme Boiler Factory By Jestarr

 

I can find it here in simtropolis but the package doesn't have the model, and it seems that could be found only on sc4devotion which is closed and sc4evermore doesn't have it (yet) available... so I cannot get rid of the brown box...

Hi @kontorotsui thanks for your comment!

The quick answer is because I do not own the models. The models were created by someone else and I cannot just package them up and redistribute them on my own. It is a significant burden to download everything, and there is work being done on that front. sc4pac is a sort of package manager that could automatically handle this for you - once all of the necessary dependencies are logged into the sc4pac system, you could tell it you wanted to download this file and it would download and collect and extract every dependency for you automatically. It requires significant effort to get all of those dependencies logged in there, though it's something I'm actively working on (I just submitted my first things into sc4pac this past weekend ). It's a relatively new tool so there's not too many things in there and there's no UI yet, but it's the future of how I think we'll eventually start distributing our content.

Re: Acme boiler, I believe they are part of BSC MEGA Props - JES Vol03, now found in the BSC Common Dependencies.

Hi, thanks for your nice reply, yes indeed I found that Acme Boiler was already covered in that prop volume. The cleaningtool listed the missing ones, still a lot.
I understand the reasons, it is a due courtesy to the authors of the model.
The big problem is that at least one of those models is positively missing and I cannot find it, that too was in the now defunct sc4devotion site and I could not find it anywhere. I'm not at home now so I cannot check which one but I'm pretty sure there is at least one.
If you want I can make a list of the ones that cannot be found, at least for those models, since they cannot be found anywhere, would it be possible for you to set up a temporary download place, since you worked on the mod you surely have a local copy of all of them.

I have used the sc4pac, for another nightmare (to install, but great to use) mod: the CAM agricoltural. That one had a lot of stuff in sc4devotion that went missing, but thanks to sc4pac I managed to download everything from all around automatically and it took only the time to merge the missing pieces in the plugin directory.

 

Hi @nos.17,

Just to be sure I did it right, I've got the "IRM_ModifiedToWorkWithCAM_B.dat" file in the highlighted folder. It should load after both CAM folders?

Yep, that should work. Let me know if not. This is on my list to get added to sc4pac sooner rather than later anyways.

Hey,

I've been trying to get get these expansions and add-ons to work in my SimCity 4 installation but I am having a hard time with it.

When I only put the SC4model files in my dependencies folder the cleanitol seems to not recognise it's presence. When I only install the mega dependencies pack (via SC4Pac) cleanitol fails to recognise any dependency. 
When I install a building dependency in full (including it's associated lot) the cleanitol starts noticing the presence of both the specific building and whichever dependency is in the mega pack. Will issues arise if I keep these lots installed?

Hi, it's been a long time since I looked at this, but I would err on the side of an error with the cleanitol script or program being wrong. It was put together before sc4pac was a thing. I would say put things together in sc4pac to the best of your abilities and if you run into boxes we can go from there to work things out.

This is currently on my list to add into sc4pac sooner rather than later, but I'm working on another project at the moment.

Thank you for the response! I was assuming the problem laid with me. With the superb Advanced Lot Plop mod I could check in-game which lots had their dependencies installed and which ones had duplicate lot files. A bit of manual work but the industrial parks will be worth it.
